Not really. On the shroomery RR mentions somewhere that it is important for the mycelium to be able to breathe (duh) and that you really need vented dishes.. I guess the plastic ones are more closed off/tightly fitted than the glass ones, so it might be helpful there. Glass ones are not airtight, the lids fit pretty loosely. I have been getting good results with non vented glass dishes, but if you go polystyrene I would say why not go vented, shouldn't be very much more expensive. Glass ones are hard to find vented.
Getting some extra non vented dishes as soon as I can, I am running out.
In looking around the fora today I found a post where it is mentioned that 60mm dishes should be more efficient than 100mm dishes in that there is more mycelial growth. I'm not sure of the specifics of it.
I now work with 80mm dishes and find those big enough, but was thinking or going bigger for my new ones. 60mm should be fine too and might be more efficient in the sense that you use less agar as well - of course they will be done quicker too! I think I'll just keep it uniform and stick with 80mm myself.
